DEVICE FOR OILING SHAFT-BEARINGS.

To all lwhom t may concern Be it known that I, FRANK R. ASHTON, a citiyen of the United States, and resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Devices for Oiling Shaft-Bearings, of which the following is a specification.

This invention relates to devices for oiling shaft-bearings, of the type adapted to be mounted upon a shaft-hanger and to be operated from below when it is desired to feed oil to the shaft-bearing in the hanger.

@ne object of the present invention is to produce a shaft-oiler of simple and inexpensive form, and to this end I employ a novel and simple construction and arrangement of the piston, by which the oil is forced from the oiler, and of the means by which the piston is actuated.

Another object of the invention is to provide, in a convenient and simple manner, for filling the oil-cylinder or reservoir with oil, and to this end I employ, in connection with the piston, a piston-rod, and an actuating-yoke with which the piston-rod is detachably connected in the manner hereinafter described.

In the accompanying drawings Figure 1 is a side-elevation of a shaft-oiler embodying the present invention, together with a portion of a shaft-hanger upon which the oiler is mounted; F ig. 2 is a plan-view of the shaft-oiler; and Fig. 3 is a vertical section on the line 3-3 in Fig. 1.

The illustrated embodiment of the present invention has a single cylindrical oil-receptacle 5, which is provided at the bottom with two lateral projections 6, perforated to provide oil-outlets. From these outlets tubes 't' project upwardly to the point of discharge of the oil. The oiler is shown as used in connection with a shaft-hanger having the usual shaft-bearing S, and the oil-tubes 7 extend to a point where they may discharge into the two oil-holes usually provided in such a bearing. As a convenient means for mounting the oiler upon the shaft-hanger it is provided with a long screw 9, which may be substituted in one of the usual adjustingscrews of the shaft-hanger, this screw passing through an opening in a bracket 10 projecting integrally from the upper end of the cylinder 5, and being locked in position therein by means of a lock-nut 11. The oil is expelled from the cylinder through the Specification of Letters Patent.

oil-tubes by means of a piston 12, which is provided with suitable packing-material, and this piston is actuated by a stem or piston-rod 13, which proiects upwardly and has a portion 11 of reduced diameter at its upper end, this portion terminating, above and below, in shoulders.

In order that the oiler may be operated conveniently from a position beneath the oiler and the shaft-hanger, I employ actuating-mechanism comprising a yoke 16 having a lateral recess 15 into which the reduced portion 14 of the piston-rod is introduced, the rod being caused to rise and fall with the yoke through the engagement of the shoulders, on the rod, with the upper and lower surfaces of the yoke. The yoke 16 is guided, at one end, by a sliding engagement with a vertical slide-rod 17 fixed, at its upper and lower ends, in the bracket- 10, as shown in Fig. 1. The opposite end of the yoke has an extended cylindrical portion or boss 18, which is screw-threaded to receive an actuating-rod 19. The rod 19 is journaled in bearing-lugs 2O and 21 projecting from the cylinder on the opposite side from the bracket 10, and by means of a cotter 22 engaging the lug 20, and a head 23 engaging the lug 21, the rod is retained against longitudinal movement. Accordingly, when the rod is rotated its screw-threaded upper portion causes the yoke 16 to rise or fall according to the direction of rotation of the rod. To facilitate the actuation of the rod itl is provided, at its lower end, with a flattened member 24 which may be convenientlyturned by hand, or by means of a suitable implenient.

The form of connection between the piston-rod and the yoke above described facilitates the operation of filling the cylinder 5, and obviates the necessity of a special opening in the cylinder for this purpose. The rod 19 extends far enough above the cylinder so that when it has been turned to raise the yoke 16 to the upper limit of its movement, the piston 12 is drawn entirely above the upper end of the cylinder,tas shown in Fig. 3. In this position of the parts the piston may be freely removed transversely from the cylinder, by disengaging its upper end from the yoke through the laterally-openingl recess 15, as indicated in dotted lines in Fig. 3. The cylinder being thus unobstructed may be readily lled, and the piston then returned to operative position. After the yoke has been lowered suticiently to introduce the piston in the upper end ot the cylinder the piston is curely retained in operative position, and the oil will then be ted in any desired quantities by rotating the rod 19 to the necessary extent.

The connection between the piston-rod and the yoke, while readily disengageable as above described, is such that rocking movement of the yoke in the plane ot the rods 19 and 17 is resisted by the piston-rod and the piston, so that in this manner (,frainpingl of the yoke upon the rod 19, owingl to the laterally-odsetposition of the latter, is prevented, and the mechanism thus works smoothly throughout its entire range ot movement.

I claim l. A shaft-oiler having, in combination, an upright oil-cylinder open at its upper end, a piston movable within the cylinder and having' a piston-rod project-ing` upwardly 'from the top of the cylinder, a slideguide projecting upwardly from the cylinder at one side thereof, an actuating-rod journaled on the cylinder at the opposite side thereof and provided, at its lower end, with a head by which it may be turned, the upper end ot the rod projecting above the cylinder and beingscrew-threaded, and a yoke having a screw-threaded engagement, at one end, with said rod and a sliding engagement, at the other end, with the slideguide, the pistonwrod being detachably engaged with the middle portion of the yoke so that when the yoke is in its uppermostposition the piston may be disengaged therefrom and removed laterally from the cylinder to permit the cylinder to be iilled.

A shaft-oiler having, in combination, an upright oil cylinder open at its upper end, a piston movable within the cylinder and having a piston-rod projecting` upwardly from the top of the cylinder, a bracket projecting upwardly from the cylinder at one side thereof, a guide-rod fixed at its upper and lower ends, respectively, in said bracket in vertical position above and at one side of thc cylinder, an actuating-rod journaled on the cylinder at the opposite side thereof, and provided at its lower end with a head by which it may be turned, the upper end o the rod project-ing above the cylinder and being screw-threaded, and a yoke having a screw-threaded engagement, at one end, with said rod, and a sliding engagement, at the other end, with said guiderod, and an intermediate transversely open recess; the piston-rod being introduced transversely into said recess and having abntments above and below the recess to restrain the rod against longitudinal movement therein, whereby the piston, when raised entirely above the cylinder by the operation ot the shaft and the yoke, may be removed transversely from the yoke and the cylinder to permit the cylinder to be filled.
